Region 3 |
San Lorenzo River Lagoon |
||
| Pollutant: | Indicator Bacteria |
| Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL) |
| Last Listing Cycle's Final Listing Decision: | List on 303(d) list (TMDL required list)(2012) |
| Revision Status | Revised |
| Sources: | Collection System Failure | Domestic Animals/Livestock | Onsite Wastewater Systems (Septic Tanks) | Transient encampments | Urban Runoff/Storm Sewers |
| TMDL Name: | San Lorenzo River Watershed Pathogen TMDL (including San Lorenzo River, Lompico Creek, Carbonera Creek and the San Lorenzo River Estuary) |
| TMDL Project Code: | 726 |
| Date TMDL Approved by USEPA: | 07/20/2011 |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | No new data were assessed. However, a TMDL has been approved by US EPA since the 2010 assessment cycle.
Note the pollutant name has been changed from Pathogens to Indicator Bacteria. 303(d) listing decisions made prior to 2006 were not held in an assessment database. The Regional Boards will update this decision when new data and information become available and are assessed. The San Lorenzo River Watershed Pathogen TMDL (including San Lorenzo River Estuary, San Lorenzo River, Branciforte Creek, Camp Evers Creek, Carbonera Creek and Lompico Creek) was approved by the Central Coast Regional Board on March 21, 2008. This TMDL was approved by USEPA 07/20/2011. In accordance with section 2.2 of the Policy, there is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. |
| Regional Board Decision Recommendation: | This is a decision previously approved by the State Water Resources Control Board and the USEPA. No new data were assessed by the Regional Board for the current cycle. The decision has not changed.
After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list in the 'Being Addressed' portion of the List because applicable water quality standards are exceeded, pollutant contributes to or causes the problem but a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. |
| State Board Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |
